AZS-41# block, besides having the eutectic of silicon oxide and alumina oxide, contains more evenly distributed zircon oxide acicula. And among the fused cast AZS series products, its erosion resistability is the best. So it is used in the key position of glass furnace in order that these positions have the same life as others.
